The trend of printed boards in global shopping malls is to introduce blind buried hole circuit boards in high-density interconnected products, and then more useful space saving, so that the line width, line spacing is thinner and narrower.
In production, we will have the engineering review and approval of your information, if there is a problem the first time to combine with you! In order not to delay your time, the combination form you provide must be accurate.
Copper clad plate is the basic material of electronic industry, mainly used in the processing and manufacturing of printed circuit board (PCB), widely used in TV, radio, computer, computer, mobile phone, communication and other electronic products.
PCB circuit boards play an important role in life today. It is the foundation of electronic components and the highway. In this regard, the quality of the PCB is critical.To check the quality of a PCB, a number of reliability tests must be performed. The
With the reduction of the aperture, the original debris that has no effect on the larger aperture, pcb board factory, such as brush debris, volcanic ash, once remaining in the hole, will make the chemical precipitation of copper, copper plating will lose
Even the well-written and actually implemented technical specifications for PCB laminates do not specify the test items that must be carried out to determine that PCB laminates are the cause of manufacturing process problems.
The holes on the circuit board are divided into overcurrent holes, plug-in holes and installation holes.
The PCB layout determines the performance of a switched power converter. You don't have to spend countless hours debugging EMI, noise, signal integrity, and other issues associated with poor layout.
In addition to the machining technology, back drilling design and stump control also have some effects on PCB loss.
Poor insulation of copper wire will lead to arc between copper wire and copper wire. Too close between the copper trace and the path, it is easy to short-circuit risk; The lack of thickness of the circuit board can lead to bending and breaking.
After the circuit is completed, solder resistance ink is coated on the circuit as protection of the circuit. There are liquid photosensitive, heat curing and UV hardening.
Embedded copper printed circuit board has the characteristics of high thermal conductivity, high heat dissipation and saving board space, which can effectively solve the heat dissipation problem of high-power electronic components.
